AI Article Synopsis
- Chlorinated hydrocarbons (CAHs) pose significant health and environmental risks due to their harmful properties, including being carcinogenic and mutagenic.
- Heterotrophic assimilation degradation is an effective method for breaking down CAHs without causing secondary pollution, but requires a thorough understanding for practical use.
- The review covers the benefits of this degradation method, current research developments, key bacterial processes, and identifies gaps in knowledge that future studies should address.
Article Abstract
Chlorinated hydrocarbons (CAHs) threaten human health and the ecological environment due to their strong carcinogenic, teratogenic, mutagenic and heritable properties. Heterotrophic assimilation degradation can completely and effectively degrade CAHs, without secondary pollution. However, it is crucial to comprehensively understand the heterotrophic assimilation process of CAHs for its application. Therefore, we review here the characteristics and advantages of heterotrophic assimilation degradation of CAHs. Moreover, we systematically summarize current research status of heterotrophic assimilation of CAHs. Furthermore, we analyze bacterial genera and metabolism, key enzymes and characteristic genes involved in the metabolic process. Finally, we indicate existing problems of heterotrophic assimilation research and future research needs.
